This example makes a ninja fight off a horde of robots. We place our ninja on paddle 1, and our robots on all empty paddles (2-11). We make the robots Look At the robot, and use a series of Play Animation results so that the ninja and robots fight, and the robots get knocked over when they come close to the ninja.
Other ideas: make these interactions also play sound effects; try playing other animations.
Note, you can’t make the ninja look at the robots so easily, because it doesn’t know which one to look at.
